2. Some medical units use synthetic gastrodin to treat neurasthenia and neurasthenia syndrome, and the effective rates are 89.44% and 86.87% respectively. It can also inhibit the central excitation caused by caffeine and enhance the sleep time effect of pentobarbital sodium.
3. Gastrodin contained in Gastrodia elata can inhibit the central nervous system in the body and play a calming role.
4. Gastrodia elata also has the function of lowering blood pressure. Gastrodia elata can expand blood vessels, increase the permeability of blood vessels, reduce the viscosity of blood and increase the blood flow of peripheral and coronary arteries.
Extended data:
1, Gastrodia elata is suitable for growing in an environment that is cool in summer and not very cold in winter. Southwest China is mostly distributed in alpine mountain areas with an altitude of1300 ~1900 meters. Due to the high latitude and low temperature in the northeast, gastrodia elata is mostly distributed in low mountainous areas or hilly areas with an altitude of 200 ~ 700 meters. Gastrodia elata began to sprout and grow when the ground temperature was above10 ~12 degrees celsius. When it reaches 15℃ or above, the growth of gastrodia elata becomes more and more vigorous.
2. Gastrodia elata usually grows vigorously from late May to early September, when the ground temperature is 20 ~ 25 degrees Celsius. However, when the soil temperature exceeded 30 degrees Celsius, the growth of Armillaria mellea and Gastrodia elata were inhibited. When the temperature is lower than 15℃, the growth slows down rapidly, and with the temperature falling again, the growth gradually stagnates and enters the hibernation period. The annual rainfall in the producing area is above 1000 mm.
3, the average relative temperature is about 80%, rainy and humid climate conditions. It is most suitable for the growth of gastrodia elata.
